Spatio-Temporal Audio Language Modeling for Dynamic Sound Sources

Oh Hyun-Bin, Kazuki Shimada, Yuhta Takida +6

Sound events are entities with semantic identities, locations, and trajectories, but current audio-language models usually reason about clips as global event content. Conversely, s…

StereoSync: Spatially-Aware Stereo Audio Generation from Video

Christian Marinoni, Riccardo Fosco Gramaccioni, Kazuki Shimada +3

Although audio generation has been widely studied over recent years, video-aligned audio generation still remains a relatively unexplored frontier. To address this gap, we introduc…

SoundReactor: Frame-level Online Video-to-Audio Generation

Koichi Saito, Julian Tanke, Christian Simon +7

Prevailing Video-to-Audio (V2A) generation models operate offline, assuming an entire video sequence or chunks of frames are available beforehand. This critically limits their use…
